Abstract
An apparatus incorporating a chemical seal and method for removing fluids from a well is disclosed. The chemical seal is created by a foaming agent which, when in the presence of gas and fluids present in the well, and when agitated by the apparatus, creates foam between the apparatus and the walls of the well in which it operates. The foam improves the seal between the apparatus and the inner wall of the well, improving the efficiency of the apparatus in lifting fluids from the well. Furthermore, the chemical seal improves the distribution of treatment chemicals within the well as it reduces liquid flowback. Automatic recharging or reapplication of the foaming agent and/or treatment chemicals to the apparatus can be accomplished with a chemical application assembly associated with the well.
